this manual before using this product. Failure to follow all instrucons listed below may result in electric shock, re and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Always keep your work area clean and well lit. Cluered benches and dark areas
invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence
of ammable liquids, gases, or dust. Power tools create sparks, which may ignite
the dust or fumes.
• Keep bystanders, children and visitors away while operang a power tool. Distracons can cause you to lose control.
ELECTRICAL SAFETY
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges &
refrigerators. There is an increased risk of electric shock if your body is grounded.
• Do not expose power tools to rain or wet condions. Water entering a power
tool will increase the risk of electric shock. If operang the power tool in damp
locaons is unavoidable, a Ground Fault Circuit Interrupter must be used to
supply the power to your tool. Use Electrician’s rubber gloves and footwear to
further enhance your personal safety in damp condions.

PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing and gloves away from moving parts. Loose clothes,
jewelry or long hair can be caught in moving parts. Keep handles dry, clean
and free from oil & grease. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain
long hair.
• Avoid accidental starting. Carrying tools with your finger on the switch or
plugging in tools that have the switch in the “ON” position invites accidents.
• Remove adjusting keys or wrenches before switching the tool “ON”. A
wrench or a key that is left attached to a rotating part of the tool may result
in personal injury.
• Don’t overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
TOOL USE AND CARE
• Always use clamps or other practical ways to secure and support the work
piece to a stable platform. Holding the material in your hand or against your
body is dangerous and may lead to loss of control. Hold the tool firmly to
prevent loss of control.
• Do not force tool. Use the correct tool for your application. The correct tool
will do the job better and at a safer rate for which it is designed.
• Do not use tool if switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any inspections,
adjustments, changing accessories, or storing the tool. Such preventative
safety measures reduce the risk of starting the tool accidentally.
• Store idle tools in a dry and secure place , out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with sharp cutting edges are less likely to jam and are easier to control. Any alteration or modification is a misuse and may result in a
dangerous condition.
GENERAL SAFETY RULES
4
• Check for misalignment or binding of moving parts, breakage of parts and
any other condition that may affect the tool’s operation. If damaged, contact Customer Service before using. Many accidents are caused by poorly
maintained tools. Develop a periodic maintenance schedule for your tool.
Contact Customer Service to have defective switches replaced. Keep handles
dry, clean, and free from oil and grease.
• Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
• While operating, always keep the cord away from the cutting area.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury. Contact Customer Service for information for repairs.
• When servicing a tool, always use only identical replacement parts. Follow
instructions in the maintenance section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk
of electric shock or injury. Certain cleaning agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage plastic parts.
PLEASE NOTE! DO NOT TOUCH ANY MOVING PARTS WHEN THE
MACHINE IS RUNNING.
DANGER! KEEP HANDS AWAY FROM CUTTING AREA AND BLADE.
• Always keep one hand on the auxiliary handle and the other on the motor
housing. When both hands are holding the saw (machine), they cannot be
cut by the blades. Keep your body positioned to either side of the saw blade,
but not in line with the saw blade. Hold the saw firmly to prevent loss of
control. Do not reach underneath the material being cut. The guard cannot
protect you from the blade below the material. Do not attempt to remove
cut material when blade is moving. Always check that lower guard properly
closes before each use. Do not operate saw if lower guard does not move
freely and close instantly. Never clamp or tie the lower guard into the open
position. If saw is accidentally dropped, lower guard may be bent. Raise the
lower guard with the retracting handle and make sure it moves freely and
does not touch the blade or any other part. In all angles and depths of cut
check the operation and condition of the lower guard spring.
GENERAL SAFETY RULES
SPECIFIC SAFETY RULES
5
If the guard and the spring are not operating properly, they must be serviced
before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris. Disconnect the plug from power source.
Periodically remove the blade, clean the upper and lower guards and the hub
area with a degreaser and wipe it dry, or blow it clean with compressed air.
• The lower guard should be retracted manually only for making special cuts
such as “Pocket cuts” and “Compound Cuts”. Always raise lower guard by
lower guard handle lever. As soon as blade enters the material, the lower
guard must be released for all other sawing. The lower guard should operate
automatically.
• Always observe that the lower guard is covering the blade before placing
saw down on a bench or floor. An unprotected, moving blade will cause the
saw to jump, cutting whatever is in its path. Be aware of the time it takes for
the blade to stop after switch is released.
• NEVER hold the piece being cut in your hands or across your leg. It is important to support the material properly to minimize body exposure, blade
jamming, or loss of control.
• Always hold tool by the insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring or its own cord.
Contact with a “live” wire will also make exposed metal parts of the tool
“live” and shock the operator.
• DO NOT use any blades other than the DUALSAW Blades specially designed
for this tool. Other blades do not match the mounting hardware & will cause
loss of control.
• Never use damaged or incorrect flanges (drivers) or bolts. The flanges (drivers) & bolts are specially designed for your saw for optimum performance
and safety of operation.
• DO NOT turn the saw on while carrying it. Lower guard may be opened by
contact with your clothing. Accidental contact with the spinning saw blade
could result in serious personal injury.
• Never attempt to operate saw with only one blade. Kickback will occur
and send the saw towards you resulting in serious injury.
HOW TO AVOID KICKBACK
Kickback is a sudden reaction to a pinched, bound or misaligned saw blade,
causing an uncontrolled saw to lift up and out of the work piece and toward
operator.
When the blade is pinched or bound tightly by the kerf closing down, the
blade stalls and the motor reaction drives the unit rapidly back toward the
operator.
SPECIFIC SAFETY RULES
6
Kickback is the result of tool misuse and/or incorrect operating procedures
or conditions and can be avoided by taking proper precautions as given below:
• Maintain a firm grip with both hands on the saw and position your body
and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken.
• Support large panels to minimize the risk of blade pinching and kickback.
Large panels tend to sag under their own weight. Supports must be placed
under the panel on both sides, near the line of cut and near the edge of the
panel.
• Do not use dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerf causing excessive friction, blade binding and kickback.
• Use extra caution when making a “Pocket Cut” into existing walls or other
blind areas. The protruding blade may cut objects that can cause kickback.
• Depending upon use, the switch may not last the life of the saw. If the
switch should fail in the “OFF” position, the saw may not start. If it should
fail while the saw is running, the saw may not shut off. If either occurs, unplug the saw immediately and do not use until repaired. Contact Customer
Service.
• Guard against kickback if the blade binds or the saw stalls and is rapidly
driven back towards the operator, release switch immediately. Do not force
tool. Stay alert, exercise control.
SPECIFIC SAFETY RULES
WARNING!
• DO NOT let familiarity with your saw make you careless. Remember that
a careless fracon of a second is sucient to cause severe injury.
• This saw uses specially designed blades and no other type of blades
should ever be used. Other types of blades will not operate safely in this
saw & could result in serious personal injury.
• If the blades come in contact with the work piece before they reach full
speed, it could cause the saw to kickback toward you resulng in serious
injury.
• Always make sure both blades enter into the material at the same me.
Entering with only one blade will cause unexpected kickback, risking serious injury. Therefore, in the case of cung at an angle, do not approach
from the side with only one blade touching, but from the top with both
blades entering simultaneously.
• The side of the blades cannot be used for cung. Therefore, in horizontal cuts, make sure saw is not resng on the lower blade. Wedge the work
piece to prevent unexpected kickback.

tool. Following this rule will reduce the risk of electric shock, fire or serious
injury.
• Always wear safety glasses or eye shields when using this saw. Everyday
eyeglasses have only impact-resistant lenses; they are NOT safety glasses.
Following this rule will reduce the risk of serious personal injury.
• Always protect your lungs. Wear a face mask or dust mask if the operation
is dusty. Following this rule will reduce the risk of serious personal injury.
• Always protect your hearing. Wear protection during extended periods of
operation. Following this rule will reduce the risk of serious personal injury.

the risk of electric shock or fire.
• Check for damaged parts. Before using the tool, inspect all parts for damage to determine if it would operate properly and perform its intended function. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the tool’s operation. A guard or
other part that is damaged should be properly repaired or replaced. Contact
Customer Service. Following this rule will reduce the risk of electric shock,
fire or serious injury.
CAUTION! If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the top surface of the
work piece causing the blade to climb out of the kerf and jump back toward
the operator.

DUALSAW BLADES
• Keep the blades clean, sharp and properly set. Using a dull blade will place
a heavy load on your saw and increases the danger of kickback. Keep extra
blades on hand, so sharp blades are always available.
• Gum and wood pitch hardened on your blade will slow your saw down. Use
gum and pitch remover, hot water or degreaser to remove these accumulations. DO NOT use gasoline.
BLADE GUARD SYSTEM
• The lower blade guard attached to your saw is there for your protection
and safety. It should NEVER be altered for any reason. If it becomes damaged or begins to return slowly or sluggishly, DO NOT use your saw until the
damage has been repaired or replaced. Contact Customer Service. Leave the
guard in its correct operating position when using the saw.
• The guard is operating properly when it moves freely and then readily returns to the closed position. If, for any reason, your lower blade guard does
not close freely, contact Customer Service for assistance before using it.
OPERATING THE SAW
• Clamp the work piece so it will not move during the cut.
• Push the switch to ON to start the saw. Always let the blades reach full
speed before you begin to cut into the work piece.
• Apply steady and even pressure when making a cut. Forcing the saw causes
rough cuts and could shorten the life of the saw or cause kickback.
• Use the lubricating device (included) when cutting aluminum, copper, stailess steel and cast iron materials, because they have a tendency to smear and
adhere to the blades.
• Always feed material parallel to the blade. Feeding at an angle can burn the
blade and damage the blade teeth.
• Don’t place the saw on the part of the work piece that will fall off (after
the cut).
• To stop the saw, slide the switch to the OFF position.
OPERATION
CAUTION!
Don’t use the saw when the blade guard is not operating properly. The
guard should be checked for correct operation before each use. If you
drop your saw, check the lower blade guard and bumper for damage at
all depth settings before using.
15
STARTING A CUT
• Slide the switch to ON to start the saw. Always let the blades reach full
speed before you begin to cut into the work piece.
• Apply steady and even pressure when making a cut. Forcing the saw causes
rough cuts and could shorten the life of the saw or cause kickback.
• Make sure both blades enter into the material at the same time; otherwise,
unexpected kickback may result, risking serious injury.
HOW TO ADJUST THE FEED SPEED
• Feed speed is extremely important to get proper results from the saw. Feed
speed is determined by the hardness and the thickness of the material you
plan to cut. Feed speed is defined by how quickly you push the saw blades
through the material.
• Feed (for thin materials) the blades down with the teeth protruding only
10-12 mm, then move forward (or backward) for cutting.
• Feeding must be parallel to the blade. Feeding at an angle can burn the
blade and damage the teeth.
OPERATION
CAUTION!
Maintain control of the saw to make sawing safer and easier. Loss of
control of the saw could cause an accident resulting in possible serious
injury.
CAUTION!
• If the feed speed is too slow, the blades will only press down the
material rather than cutting it. The blade edges glide and wear down
the material. This will cause a poor cut and will cause excessive wear
on the blades.
• If the feed speed is fast there is a definite risk that the cut might
split. The splinter will get bigger and bigger and eventually break risking serious personal injury.
• If the feed speed is too high there is a risk that the cut might split
and the splinter opening’s volume will not be sufficient to divert all the
shaving. The result is a poor cut with significant discharge on the lower
side of the material.

MAINTENANCE
GENERAL MAINTENANCE
• Tool service must be performed by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of
injury. Contact Customer Service for information on repairs.
• When servicing a tool, always use only identical replacement parts. Follow
instructions in the maintenance section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk
of electric shock or injury. Certain cleaning agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage plastic parts.
• Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use a clean cloth to remove dirt, carbon dust etc.
• It is a known fact that electric tools are subject to accelerated wear and
possible premature failure when they are used to work on fiber glass boats
and sports cars, wallboard, spackling compounds or plaster. The chips and
grindings from these materials are highly abrasive for electrical tool parts,
such as bearings, brushes, commutators, etc. Consequently, clean the tool
even more intensely after working these materials.
CLEANING AND STORAGE
• Resin and other materials that easily become attached to the sides of the
blade often cause the blade to overheat. This means that it can buckle or
even split. You must therefore always keep the blade clean. Wash it with a
solvent. Never try to scrape the blade clean with a hard object.
18
MAINTENANCE
• When the blade is not in use, it should be stored in its original sheath, well
cleaned and coated with an antirust agent.
LUBRICATION
• All of the bearings in this tool are lubricated with a sufficient amount of
high-grade lubricant for the life of the tool under normal operating conditions. Therefore, no further lubrication is required.
DOUBLE INSULATION
• Double insulation is a concept in safety in electric power tools, which eliminates the need for the standard 3-wire ground power cord. All exposed metal
parts are isolated from the internal motor components with protecting insulation. Double insulated power tools do not need to be grounded.
EXTENSION CORDS
• The use of any extension cord will cause some loss of power. To keep the
loss at a minimum and to prevent overheating, use an extension cord that is
heavy enough to carry the current that the tool will draw.
BLADE MAINTENANCE
• Don’t use any blades other than the DUALSAW™ CS 650 blades specially
designed for this tool. Other blades do not match the mounting hardware
and will cause loss of control.
• Do not use dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerf causing excessive friction, blade binding and kickback.
• Keep the blades clean, sharp and properly set. Using a dull blade will place
a heavy load on your saw and increases the danger of kickback. Keep extra
blades on hand, so sharp blades are always available.
• Gum and wood pitch hardened on your blade will slow your saw down. Use
gum and pitch remover, hot water or degreaser to remove these accumulations. DO NOT use gasoline.
• Don’t attempt to operate saw with only one blade. Kickback will occur and
send the saw toward you resulting in serious injury.
WARNING!
When servicing, use only identical replacement parts. Use of other
parts may create a hazard or cause product damage.
Contact customer service at 1-855-382-5729 for information on how
to obtain replacement parts from an authorized service facility.
